In today’s data-driven world, geospatial data is more important than ever. From urban planning and environmental conservation to navigation and real-time tracking, the ability to view and analyse geographic information is crucial. But you don’t need expensive software to get started. Whether you’re a professional GIS analyst, a student, or a curious explorer, there are several free GIS viewers available that make exploring geospatial data easy and accessible.
What’s a GIS Data Viewer?
A GIS data viewer is essentially an enhanced map that lets you visualize various types of geospatial data, such as shapefiles, satellite imagery, elevation data, and environmental layers. With this tool, you can zoom in on specific areas, such as a forest, compare flood maps, or analyse changes in land use over time.
